You can tell a C or C++ compiler to use a CPU register for a particular variable by using the 'register' keyword, however it is only a suggestion to the compiler. There is no guarantee that a CPU will be used. You can read the C standard for more about this. Also, beware of premature optimization. http://en.wikipedia.org/wiki/Optimization_%28computer_science%29
